Centri vs TVS or E Force
Lets get a decent discussion going. I hear this all the time.
About the extra TQ down low of the TVS. Please post your dyno sheets.
I perfer the Centri. Unless you have driven one lately they make good tq
down low. But in the curve shoots up wards peaking at your shift point.
Where as the TVS pushes early in the curve and ramps down.
The E Force seems to look like a combo graph of the two but at a little lower output.
Lets keep this apples to apples as far as engine size. This is a LS-3 graph.
A&A kit V-3si Vortech 9 psi
Heres a EForce graph. Actually it is a real nice TQ curve.
My Ls-7 has no sheet yet but I looked at the exact same combo
on A&A Website V/2-3 stock with headers making 678rwhp and 599 rwtq with over 500 rwtq at 3.5k.

Yes, but are they making the same power and same power curve
as the TVS? Not from what I have seen. It is a nice curve though. That why I want see more examples.

You keep saying TVS...you aren't getting it...Eaton manufactures the TVS2300 rotor group. It's the core of both Edelbrock and Magnacharger superchargers and maybe others out there. This is going to be a useless thread and I'll tell you why. You are viewing this entire discussion from a perspective of guys who live their lives 1/4 mile at a time and set their shift points at redline. There isn't going to be much of an arguement that you can build more power with a centri unit if that's your goal. It's been proven time and time again.

Keep your shirt on! This thread is to point out the good points of each. If it is useless to you stay out then. Because the output curves from the TVS2300 and the Eforce are not quite the same. If they are let see them! My perspective is street and highway driving. Not hardly quarter mile at time.

I have the e-force on my car, but I'm not saying I think one is better than the other. I would choose an A&A or ECS kit if I was running a quarter mile or any type of racing. I chose the e-force kit because I ***believe*** the part throttle response at very low rpm's is better. It's rare that I rev my car over 4000 rpm's. I'm almost always between 1500 and 2500 rpm's and the part throttle response in that range is great.
I've seen many arguments on the forum and sometimes they go overboard. I don't participate in those. It seems that every time someone starts an e-force thread, someone with a centri has to jump in and start bashing the TVS blowers.
We all have a reason for our choice. A dyno graph doesn't show the low-rpm part throttle response.
** I agree with the argument that the centri makes more power. **

I'm in the 1500-2000 range. For mileage on the highway. But when I want to accellerate it's not
at that RPM. I would be ramping up at 3k on up. Trying to make power at that RPM. I have trouble seeing the reason. Thats why all automatic's downshift.

There are some advantages to both types which everyone seems well aware of. I'm going with the E-Force because I wanted a factory look which the centri obviously doesn't have. I'm not big on lots of pipes, etc under the hood and another reason I didn't want a turbo either. It really seems pointless to dis either type simply because someone went it. Both types are available for a variety of reason.
I don't care about squeezing the last available boost and thus HP out of my FI. I don't race the car so it's simply not an issue for me. I'd much rather have more low end torque at lover rpms which the E-Force fits nicely. Not looking to build a 700 or 800 hp engine for the street... no interest what so ever.
Bottom line for me is reliability, factory look, low end torque and reasonable pricing. The E-Force meets all my personal specs so it was an easy choice.... That certainly doesn't mean it's the BEST system, only the one I believe it BEST for me....

I want drive one. I already looked at the install instructions

Want to stay away from the arguement part but expose the truth or myth as to whatever it maybe.

It may just be a preference in driving style. I don't rev it up that often.
Everyone has an opinion on this subject. I like the centri's too and would own either without a problem.

If I wanted to spend the time and money to hook it from a dig, I think it would compete pretty well with a centri at similar boost levels. Yes, the centri will hook easier at similar power levels. It doesn't make as much power when trying to hook. That's not that hard to understand. Most folks that install maggies really aren't that interested in all out drag strip performance. Do-able, but I have no interest in trying to hook that much power from a dig. You'd have to turn a really nice street car into a dedicated drag car. Not my cup of tea.
You do need to drive one, or at least ride in one. Eye opener.

Heat is an issue for me. The temps I get w/ a centri would only be exaggerated further if I'd had a top-mount.
I love the beastly curve of a top-mount, but like the "stock" around-town drivability of the centri more. I have very little want or need for 500+ ft/lbs below 2K rpm. If I want it, I just drop a gear and mash the gas.
I also plan on upping the boost later, after a couple more supporting mods. A TVS/E-Force is pretty much limited by design to the amount of boost it can push. The only other options are turbo (too expensive), nitrous (no thanks), or a centri.
